SCALE.

Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed July 21, 1905. Serial No. 270,614:-

To all whom, it may concern:

Be it known that I, JOHN A. 'RISHEL, of Homestead, Allegheny county, and State of Pennsylvania, have invented a new and useful Improvement in Scales, of which the following is a full, clear, and exact description,

drawings, in which Flgure 1 1s a side elevatlon of ascale-beam box, showing my lmproved beam-carrier and the scale-beams in position on the car rier and also showing the manner in which the scale-beams are held out of engagement Fig. 2 is a sectional plan view of the scale-beam box, showing the scale-beams and the beam-carrier in the box. Fig. 3 is an end elevation of the box, showing the pawls by which the scale-beams are held when lifted and the hinged latch by which the beams are tilted on their pivots; and Fig. 4 is a sectional view on the line IV IV of Fig. 1, showing the cross-arm of the beam-carrier on which the front ends of the scale-beams are carried when in engagement with the beam-carrier.

My invention relates to scales having a horizontal arrangement of scale-beams by which a number of different materials of varying amounts are weighed, either singly or collectively, by moving the required scalebeam into engagement with the scale-beam carrier.

The invention consists in providing a scale-beam carrier which is pivoted in suit able pivot-bearings in the chair or pivotstand located in the beam-box and in providing novel means by which each of the series of horizontally-arranged scale-beams is pivoted in pivot-bearings on the chair, which are independent of each other and of the beam-carrier.

It also consists in providing means on the front end of the beam-carrier, which engage with the scale-beams in weighing.

The invention also consists in providing means by which the scale-beams are tilted so as to be out of engagement with the beamcarrier and means for holding the scalebeams out of contact with the beam-carrier until released by the scale-operator.

In the drawings, 2 represent the beam-box of the scale, in which the beam-carrier 3 and scale-beams 4 are located. The beam-carrier 3 is pivotally mounted in suitable pivotbearings 5 5 on the pivot stand or chair 6, also located in the box 2, and each of the series of scale-beams is also pivoted in pivotbearings 7, which are separate from each other and from the beam-carrier. By means of the stops 8 9, located on the inside of the front end of the box, the lift of the pivoted j beam-carrier 3 is limited and its upward and reference being had to the accompanying downward movement is controlled. The front ends of the scale-beams 4, which beams I are also pivoted on the chair 6, project through suitable slots 10, located in the end of the box 2, and the end of each scale-beam is provided with a longitudinal slot 11.

Pivoted to the front end of the box 2 are pawls 12, which by engagement with the slotted ends 11 of the scale-beams 4 hold the beams out of engagement with the beamcarrier 3 until released by the scale-operator. Also pivoted on the front end of the box 2 is a hinged latch 13, provided with a handle 14, by which the latch is operated to lift the scale-beams out of engagement with the beam-carrier. The handle 14 is counterweighted to normally hold the latch 1.3 in its inoperative position.

The beam-carrier is connected, by means of the links 15 16 and the rod 17, to the scalelevers. (Not shown.) The beam-carrier is provided with the usual poise l8, counterbalance 19, and the back balance 20, which are adj ustably held in position on the beamcarrier, the poise and back balance being secured in the desired position by means of setscrews 21 22, the counterbalance being adjusted on its adjusting-screw 19. Each scale-beam is graduated and is provided with a counterbalance 23, by which it is balanced on its pivot, and with a poise 24, both of which are adjustably secured to the scalebeams by set-screws 25 26. The beam-box 2 1s providedwith a hinged side or door 27,

which when open gives access to the movable parts of the beam-carrier and the scale-beams and when closed and locked or otherwise secured prevents the adjustable parts of the beam-carrier and scale-beams from being shifted or otherwise tampered with.

In the operation of the apparatus first the beam-carrier and scale-beams are balanced. The poise on each of the graduated scalebeams is then set to the desired point and secured in this position by means of its setscrew. The hinged door is then closed and secured. By means of the hinged slide the operator then raises all of the scale-beams on their pivots, so as to be out of engagement with the beam-carrier, and they are held in their inoperative position by the pawls. The operator then releases the scale-beam corresponding with the amount desired to be weighed on the scale, and when the required weight is on the scale the carrier and scalebeam will indicate the same by tilting, as in the ordinary beam scale. An additional amount may be weighed without removing the first amount from the scale by releasing another of the scalebeams. tions may be made to the load upon the scale,

.or the load on the scale may be removed,

when the operation described above may be again repeated.

The advantages of my invention will be apparent to those skilled in the art. Instead of pivoting the scale-beams on the main beam, as in the usual scale, each scale-beam is pivoted independently of the beamcarrier and of each other. Instead of lifting the scale-beams out of engagement with the pivot-bearing on the main beam, as in the constructions used heretofore, the scalebeams are tilted on their pivots, so as to clear the front end of the beam-carrier.

Modifications of the construction and of the arrangement of the parts may be made without departing from my invention, since What I claim is 1. In a scale, the combination with a pivoted carrier of a plurality of scale-beams pivoted independently of the carrier, mechanism engaging with and simultaneously raising the entire series of beams out of engagement with the carrier, means for operating the beam-raising mechanism and means engaging with and holding each individual Further addibeam in its raised position substantially as described.

2. In a scale, the combination with a pivoted carrier, of a plurality of scale-beams pivoted independently of the carrier, a hinged latch by which the entire series of beams are simultaneously raised out of engagement with the carrier, means for operating the hinged latch, and means engaging with and holding each individual beam in its raised position; substantially as described.

3. In a scale, the combination with a pivoted carrier of a plurality of scale-beams pivoted independently of the carrier, a hinged latch by which the entire series of beams are simultaneously raised out of engagement with the carrier, means for operating the hinged latch, and a pawl engaging with and holding each individual beam in its raised position substantially as described.

4. In a scale, a weighing-beam comprising a beam-carrier, a series of horizontal scalebeams, side by side between the sides of the beam-carrier, a pivot-stand provided with pivot-bearings for the carrier and with independent pivot-bearings for each scale-beam, a pawl for each scale-beam for holding the beams out of engagement with the beam-carrier and a hinged latch by which the scalebeams are lifted out of engagement with the beam-carrier; substantially as described.

In testimony whereof I have hereunto set my hand.
